Hello Everyone,

I am facing a few problems when trying to mesh my NACA 0009 airfoil with a plain/slotted wing flap using blockMesh. The exact problem entails highly skewed cells in the interface between the circular gap (between the foil and flap) and the outbound rectangular box (I am using a C-type mesh).

I tried defining various blocks and manipulating the vertices around, but no luck so far. Please find attached my blockMesh file, as well as, a picture of the problem. Your help is much appreciated.

It is currently failing 2 mesh checks, I suspect they are both related to the high skewness involved.
